# White Balance
This code snippet shows how to perform white balance.
## C++
```cpp
#include
#include
```
```cpp
using namespace eVision;
// Images constructor
EImageC24 srcImage, dstImage;
EImageC24 whiteRef;
// ...
// Create a lookup table
EColorLookup lut;
// Measure the calibration values from a white reference image
EImageStatisticsC24 stats;
stats.SetImage(&whiteRef);
std::vector rgb = stats.GetPixelAverage();
// Prepare the lookup table for
// a white balance operation
lut.WhiteBalance(1.00f, EasyColor::GetCompensateNtscGamma(), rgb[0], rgb[1], rgb[2]);
// Source and destination images must have the same size
dstImage.SetSize(&srcImage);
// Perform the white balance operation
lut.Transform(&srcImage, &dstImage);
```
